The effects of classical factors, such as symbol geometry, symbol brightness, and brightness contrast, upon the legibility of numerals and capital letters are discussed. Included is a consideration of the literature of the last few decades relevant to the specification of acceptable operator performance criteria which must be met by a given…

This paper reports initial results in the development of an inventory to measure visual reading difficulties. The instrument, called the Word Preference Inventory (WPI), asks the subject to choose between pairs of stimulus pseudo-words the one most like a given target word. An analysis of responses to the WPI from 922 children in grades K-6 and…

Research indicates that young children seem to have considerable difficulty in discrimination between the letters b, c, p, and q. Also, 4-year-olds appear to commonly make rotation and reversal errors with letter-like forms. Whether young children will perform significantly better or not in deciding whether two shapes are called same or different…

An application method for evaluating the visual significance of reflected glare is described, based upon a number of decisions with respect to the relative importance of various aspects of visual performance. A standardized procedure for evaluating the overall effectiveness of lighting from photometric data on materials or installations is needed…

Describes an experiment revealing a visual latency effect produced by the wearing of sunglasses. (SL)

Presents an overview of some of the major concerns for teachers of Image Study in higher education and offers examples of image sets useful for concept teaching. (MH)

Offers a brief student analysis of the visual elements which compose the front pages of two daily British newspapers in a single day. (MH)

Four experiments assessed converging aspects of four-month-old infants' perceptions of visual patterns. Results together corroborate and extend previous findings that vertical symmetry has a special status in early perceptual development and that infants can perceive pattern wholes. (Author/AS)

Infants at two age levels were shown six patterns which represented three levels of stimulus complexity and two types of organization, facial and nonfacial. Results agree with previous studies in suggesting a change between ages 10 and 15 weeks in dimensions which underlie infants' response to facelike patterns. (Author/HS)

It was concluded that drawing rules are essential and that adequate visual analysis is a necessary but not sufficient prerequisite to the production of accurate copies. (Author)
